Power supply of the auxiliary circuits by means of transformer with electrostatic protection between primary and secondary winding.

Terminal blocks for outer connections.

Wiring with flame retardant cables.

Protection degree of internal components against accidental contact IP2X or IPXXB.

Control system via PLC and touch-screen type operator interface.

PRESS AUTOMATION SYSTEM

Control system based on a PLC and an operator interface (HMI) to respectively control and supervise the entire process.

Main system features

AUTOMATIC PROCESS MANAGEMENT

Automatised production start and production stop. The system provides automatic management of the transitory production sequences, of the cycles and particular sequences, as well as of the synchronisation of the various machines.

MANAGEMENT OF SYNOPTIC PANELS

Animated synoptic diagrams about the controlled plant, with indication of the status of the various users (functioning mode, automatic/manual, maintenance, etc.).

MANAGEMENT OF MOTORS AND USERS IN AUTOMATIC AND/OR MANUAL MODE

The system is set to manage automatically of all motors, but it is also possible to force to manual mode the functioning or stop of each single motor (e.g. for maintenance, test, etc.) 

DISPLAY OF ALARM MESSAGES

Display of active alarms, with indication of intervention date/time and restore date/time for each single anomaly. Also the acknowledgement, restore and plant restart in case of anomaly are carried out by means of the operator interface.

MANAGEMENT OF PRODUCTION RECIPES FOR EACH SINGLE PRODUCT

Each single product can utilise different combinations of process parameters. These parameters are memorised for each recipe and can be loaded and used as set-point values at the beginning of production.

MANAGEMENT OF REGULATION LOOPS

Detailed display of each single regulation PID is possible. The regulation loop can be completely parametered from the relevant menu: setting of low and high limit, threshold alarms, deviation alarms. Furthermore, the PID parameters can be displayed in form of real-time curves, which makes the parameterisation of each single loop extremely easy.

TELEMATIC ASSISTANCE

This package, including hardware and software, allows the connection by modem and telephone network between the plant control system and the Pavan Telematic Assistance Centre. The Telematic Assistance Centre provides complete and efficient diagnostics of both technology and automation system, as process conditions can be monitored during the various production steps. 

The software for plant control can be easily updated.
